港口岸线资源使用许可拍卖模型

为揭示我国港口岸线资源的真实价值,运用拍卖模型和博弈理论,论证英式拍卖与一级密封价格拍卖模式对港口岸线资源使用许可证拍卖的适用性和有效性,分析不同拍卖模式下的投标者最优报价策略和政府期望利润,建立港口岸线资源使用许可拍卖模型,并进行数值仿真.结果表明:对于政府而言,英式拍卖与一级密封式拍卖能带来同等的期望利润,拍卖人数较多情况下,各拍卖者在一级密封价格拍卖过程中报价无限接近其真实报价;对于投标人而言,相较于英式拍卖,一级密封价格拍卖能产生一定预期收益,因此投标人更倾向于一级密封价格拍卖模式.

Trust,reputation and ambiguous freedoms: financial institutions and subversive libertarians navigating blockchain,markets, and regulation

This article departs from the post 2008 financial crisis context, from its intersection with technological developments, and from the socio-technical arrangements configured by this conjuncture. It explores plans and actions – of mainstream financial institutions, and of a community seeking for alternatives to centralised economy and governance – for the use of digital platforms supported by blockchain infrastructure. In particular, it explores how such plans and actions relate to conceptions of public and peer trust and how they appear to produce, or reinforce, reputational imaginaries and quantification practices within added value philosophies. By illuminating a tension between the two identified case examples, I seek to render alternative communities’ and financial institutions’ conceptions, imaginaries and practices (more) visible and to analyse their organisational marketing strategies – where there is a pragmatic and discursive operationalisation of technology as well as of trust as means to gain more self-sovereignty in action, while navigating markets and regulated actual world contexts.     

非对称收费模式下平台横向合并的经济效应研究

以双边平台竞争瓶颈理论框架为基础,考虑同一平台在一边收取注册费、在另一边收取交易费的非对称收费模式,并将已有平台竞争模型拓展至Salop圆形市场情形后,探讨了平台横向合并的经济效应。与已有研究强调间接网络效应、市场势力和成本效率提升三者之间的权衡不同,本文研究发现：在非对称收费模式和市场全覆盖假设下,平台合并的价格效应和福利效应仅与平台间横向重叠导致的市场势力提升与成本效率提升之间的权衡有关,而与间接网络效应无关;如果边际成本较小,则效率抗辩空间会主要集中于降低经营（固定）成本等方面。研究结论不仅可以丰富经济学关于平台合并的理论研究,也可为反垄断执法部门针对平台领域经营者集中审查提供理论借鉴。     

Determinants of Prices for Contemporary Art in Dutch Galleries, 1992–1998

We analyse determinants of prices for contemporary art with the help of quantitative data. The focus is on gallery rather than auction prices in the Netherlands. We model the determinants of prices on three different levels: the work of art (size, material), the artist (age, sex, place of residence, institutional recognition), and the gallery (location, institutional affiliation, age). Our main findings are that the size and material of works of art, and the age and place of residence of the artist are strong predictors of price; that differences in size and materials partly ``mask' price differences between artists; and that the variance in prices across galleries is largely explained by characteristics of the artists they represent.     

新疆入境旅游客源市场结构的研究

在描述性分析的基础上,选用2000—2012年13年数据,运用聚类分析方法对新疆入境旅游客源市场进行分类,以期优化新疆入境旅游客源市场结构。结果表明：新疆入境旅游客源市场大致可分为6类,其中欧洲市场中俄罗斯入疆人数较多,亚洲、美洲、大洋洲市场入疆人数相对较少;并且近程市场所占份额远超过远程市场。针对这些情况,提出了4条拓展新疆入境旅游客源市场的对策建议。     

Not all scientists pay to be scientists: PhDs’ preferences for publishing in industrial employment

It is often assumed that academically trained scientists have a strong taste for science and are willing to “pay” for the ability to openly disclose their research results. However, little is known regarding how scientists considering jobs in industrial R&D make trade-offs between positions that allow publishing on the one hand and positions that do not allow publishing but offer higher pay on the other. Using data on over 1900 science and engineering PhD candidates about to enter the job market, we find that while some are unwilling to give up publishing at virtually any price, over one third of those most likely to seek positions in industrial research are willing to forego publishing for free. We develop a simple model of the “price” scientists assign to publishing in firms and explore potential sources of heterogeneity empirically. We find that the price of publishing increases with individuals’ preferences for various benefits from publishing such as peer recognition and contributing to society, but it decreases with their preference for money. Scientists who believe themselves to be of high ability and who train at top tier institutions have a higher price of publishing. Yet, they are more expensive to hire (not less) even if publishing is allowed. We discuss implications for research on the economics of science and on compensating differentials, for managers seeking to attract and retain academically trained personnel, and for firms considering their participation in open science.     

制度环境、国际市场进入模式与国际创业绩效

本文基于动态能力理论和制度理论,通过对112家国际创业企业进行问卷调查,运用层次回归分析模型对制度环境、国际市场进入模式和国际创业企业绩效三者之间的关系进行实证研究。结果表明:国际市场进入模式与国际创业企业绩效正相关,管制、认知和规范制度环境在国际市场进入模式与国际创业企业绩效关系中扮演着负向的调节作用。
